Testing multi-characteristic product capability indices

The International Journal of Advanced Manufacturing Technology, 2006
Recently, studies associated with testing the quality and performance of each process for a product with multi-characteristics are proposed more often. However, most studies are limited to discussing one single type of quality characteristic. Practically, a multi-characteristic product is potentially composed of three types: smaller-the-better, larger ...

Process capability indices and product reliability

Microelectronics Reliability, 2001
Abstract This paper discusses process capability indices— C p and C p k , their underlying assumptions, and the relationships between process capability indices and product reliability. An actual case is presented to demonstrate this relationship.

Bootstrap test for process capability indices

International Journal of Quality & Reliability Management, 2017
Purpose The purpose of this paper is to construct a statistical hypotheses test for process capability indices and compare the pairs of them with a fixed sample size. Design/methodology/approach Since the sampling distribution of the estimators of pairs of two process capability indices (PCIs) is very complex, an exact statistical hypothesis test ...

Process capability indices

The thesis is introduced and studied the initially capability indices and their youngest indices which appeared for the improvement of capability indices. The majority of the work refers to one-dimensional characteristics of normal distribution, but there is an important reference in multi-dimensional of normal data. In the first chapter we will define

Process capability indices for skewed populations

Quality and Reliability Engineering International, 2002
AbstractThis paper proposes a new method of constructing process capability indices (PCIs) for skewed populations. It is based on a weighted standard deviation method which decomposes the standard deviation of a quality characteristic into upper and lower deviations and adjusts the value of the PCI using decomposed deviations in accordance with the ...

Basic Process Capability Indices: An Expository Review

International Statistical Review, 2008
Summary A review of the four basic process capability indices has been made. The interrelationship among these indices has been highlighted. Attention has been drawn to their drawbacks. The relation of these indices to the proportion nonconforming has been dwelt upon and the requirement of the adequate sample size has been emphasized.

Monitoring of the Measurement Process Capability by Using Capability Indices

2019
Requirements related to accuracy of measurement and other metrological properties are required for measurement. Expression of the quality of the measurement is generally solved by the uncertainty of measurement. For measurements in industry, in addition to uncertainty increasingly also used capability index.

Multivariate Process Capability Indices (MPCI)

2012
In this chapter the most recognized multivariate process capability indices are presented. The first section approaches the computation of these indices in R, and the next ones are dedicated to the indices based on ratios of the volume tolerance region to a process region such as Taam et al. (J Appl Stat 20:339–351, 1993), Shahriari et al. (Proceedings
